" IMPROVEMENT IN SUGR-CANE-CRUSHING MILLSl Spccilication forming part of Letters Patent N0. 36,156, dated August 12, 1862.

To @ZZ wiz/0m, it may concern,.-

Be it known that l, ALFRED INGALLs, of Independence, in the county of Buchanan and State of Iowa, have invented certain new and useful Improvcmentsin Sugar-Cane Crushers;

` and Ido hereby declare that the fol-lowing is crushing-rollers, by means of which the stalks of cane are slit or cut into strips previous to entering` between the crushing-rollers,thereby allowing the slitted cane to spread over a greater space between the rollers than would be the case with whole stalks, thus giving a more perfect pressure than could otherwise be obtained.

A A represent the crushing-rollers, and a a their shafts or journals. These are Inadein the usual form, and connected with suitable gears, and placed in a 'propery frame .work either horizontally or vertically. These rollers are intended to rotate in the direction of the arrows in Fig. 2.

The revolving cutters consist each of a shaft, B B', about two inches in diametenand of the length of the crushing-rollers A A, and provided with journals and boxes set in the frame of the machine. The space between the shafts B B is about one inch, and each shaft is provided with a series of thin circular cuttingblades or cutters, C C, Ste., which are placed upon the shafts B B', and may be separated by collars D D, or by other means which will keep the blades C C about half an inch apart, the cutters being so secured to the shafts that they mustrotate with them. The cutters on the shafts B are so placed and secured as to be alternate with the cutters on the shaft B, and all the c utters are of sufficient diameter to reach nearly to the collar D on the opposite cutter-shaft. Thus the space between the cylinders or shafts B B is divided into sec-v tions of about one-fourth of an inch bythe alternate revolving cutters C C. The shafts B B are furnished with gear-wheels or pulleys and belts, which cause them to revolve in the direction of the arrows in Fig. 2, and with the same surface velocity and in a corresponding direction with the rollers A A. Now, if canestalks are fed into the machine and caused to Vhat I claim as my improvement, and desire to secure by Letters Patent, is-

The revolving cutters C C, arranged and operated in combination'with the pressing-rollers A A', as specified.

ALFRED INGALLS.
